T0 @ZZ whom t may concern.l

Be it known that I, EDMUND LEREDE GHALKE, a subjectof the Queen of GreatBritain, residing at Cocanada, in the Madras Presidency, India, haveinvented certain new and useful Improvements in Commodes, (for which Ihave obtained a patent in India, No. 904, bearing date March 23, 1895and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvements in commodes; and it has for itsgeneral object to provide a commode embodying means for automaticallyclosing the seat-opening and means for automatically covering theevacuation with sand or dry earth after the commode is used, so as toprevent to a great eX- tent the generation of noxious odors and gases.

Another object of the invention is to provide a commode embodying meansfor receiving urine and conveying it to a point of discharge or aseparate receptacle arranged to receive it, so as to prevent it frommingling with and retardin g the desiccation ofthe eva cnations.

Other obj ects and advantages of the invention will be fully understoodfrom the following description and claims when taken in conjunction withthe accompanying drawings, in which-V Figure 1 is a longitudinal centralsection of myimproved commode. Fig. 2 is a plan view of the same, partlyin horizontal section, the said section being taken in the planeindicated by the line oc of Fig. l. Fig. 3 is a vertical transversesection taken in the plane indicated by the line w w of Fig. 1. Fig. 4is a similar view taken in the plane indicated by the line y y of Fig.l, and Fig. 5 is a detail enlarged section taken in the plane indicatedby the line e' z of Fig. 1.

In the said drawings similar numerals designate corresponding parts inall of the several views, referring to which- 1 indicates the box-likebody of my improved commode, which is preferably of rectangular form, asillustrated.

2 indicates compartments at the opposite ends of the body, and 3indicates the verticallymovable seat, which serves as a lid or cover forthe body 1 and has the opening 4 of suitable shape and size, and alsohas the depending langes 5 surrounding the body, as illustrated. Thesaid seat 3 is arranged and adapted to move upon guide-posts 6, risingfrom the corners of the body 1, and it bears and is supported upon theantifriction-wheels 7, carried at the inner ends of levers 8. Theselevers 8, which are arranged in pairs at opposite ends of the body 1,extend through the end walls of said body and are fulcrumed therein, andthe outer ends of said'levers are connected by receptacles 9, whichcarry weights 10, as better illustrated in Fig. l oi' the drawings. Invirtue of this construction it will be observed that when the seat 3 isoccupied the weights 10 will be overcome and the seat will be depresseduntil it rest-s upon the body 1, and it will also be seen that when theseat is vacated the weights 10 will rock the levers and raise the seatto its normal position, slightly above the body 1, and hold it in suchposition.

Connected in a flexible or hinged manner to the levers 8, adjacent tothe outer ends thereof, as indicated by 12 in Fig. 2, are links 13,which have their opposite ends bifurcated, as indicated by 14. Saidbifurcated ends oi' the links 13 receive and are exibly connected to thebifurcated ends l5 of slide-bars 16, which extend through openings 17 inthe end walls of the body 1, into the interior of the same, for apurpose presently described. The pintles 13, which connect the links 13and the bars 1b', form journals for wheels 19, which are arranged anddesigned to travel on tracks 20, so as to facilitate the movement of thebars 16 and links 13 and the parts connected therewith. The said tracks20 are supported on brackets 21, which are tixedly connected to the endwalls of the body 1, and in order to prevent displacement of the wheels19 from the tracks the clips 22 are provided, which are looselyconnected to the pintles 18 and loosely receive the horizontal bars ofthe brackets, as illustrated.

The bars 16 are connected at about the point shown by the transversebars 23, and to these bars are hinged iiaps 24, which, when the seat 1is occupied, are caused to assume a horizontal position by reason oftheir portions contiguous to the bars 23 being drawn through ICO theopenings 17 in the end walls of the body. Then in such horizontalposition, the said flaps 24 are designed to receive sand or dry earthfrom sources presently to be described, and when the seat 3 is vacatedand the links 13, bars 1G, and bars 23 are moved inward by the action ofthe weights 10 they are designed to drop, as shown in Fig. 1,'so as todischarge the dry earth or sand on the evacuation in the body 1. Thisdeposit of sand or dry earth is made upon each evacuation, and eachevacuation is covered thereby, and consequently the generation of odorsand noxious gases is to a great extent prevented and at the same timedesiceation of the evaeuations is facilitated.

25 indicates shutters which are designed to close ,the seat-opening 4,as shown in Fig. 1, so as to hide the interior of the commode from view.These shutters 25 have antifriction-wheels 2G on their under side, whichJtravel upon tracks 27, fixed in the body 1, (see Figs. 1, 2, and 4,)and they are connected to uprights 2S, which rise from theinner ends ofthe bars 16, whereby it will be seen that when the sea-t 3 is depressedthe shutters will be opened or moved toward the ends of the body 1, andwhen said seat is vacated the shutters will be closed or moved togetherbeneath the opening 4 and held in such position, so as to hide theinterior of the body l from view.

29 indicates boxes which are arranged at opposite ends of the body 1 ina plane above the tlaps 24. These boxes have hinged bottoms 30, whichextend through openings 31 in the end walls of the body, as shown inFig. 1, and are connected by rods with arms 33, conneeted with the seat3, whereby it will be seen that when the seat is depressed, the bottoms30 will also be depressed so as to permit the sand or dry dirt to passfrom the interior of the boxes into the body 1 and on the iiaps 24,which will then be in a horizontal position, as before described.

Sand or dry earth is let into the boxes 29 through the tubes 34, whichare connected with reservoirs (not illustrated) by pipes, (also notillustrated.) Communication between these tubes and the boxes 29 iscontrolled by the valve-gates 35, which take through slits 3G in the topof the boxes, adjacent to the side thereof, as better shown in Fig. 3,and are connected at their upper ends with the arms 33. In virtue ofthis it will be seen that when the seat 3 is in its normal raisedposition the valve-gates 35 will be open, so as to permit sand to enterthe boxes 29, and when the seat is depressed and the bottoms of theboxes are in their open position the valve-gates will be closed, so asto prevent sand from passing from the tubes 34 into the boxes. In otherwords, when the bottoms of the boxes are closed sand will be permittedto pass into said boxes until they are filled, and when said bottoms areopened by the depression of the seat 3 the supply of sand to the boxeswill be out oit and the sand in said boxes will pass from the bottomsthereof onto the ilaps 24, which are then in a horizontal position. Thenthe seat 3 is vacated, the bottoms of the boxes 29 will be closed, thevalve-gates 35 will be opened, and the flaps 24 will be moved inwardlyand permitted to fall, so as to discharge the sand or dry earth upon theevacuation for the purpose before described.

It will be observed from the foregoing that my improved commode isentirely automatic in its action; that is to say, it is closed aftereach use and the evacuation is covered without attention on the part ofthe user.

37 indicates a urine-receiver which is fixed in the body 1 in front ofand partly beneath the opening 4 in the seat. To this receiver 37 isconnected a pipe 3S, which leads down through the body 1 and is designedto conduct the urine to a point of discharge outside the body 1. Thepurpose of thus carrying off the urine is to prevent it from minglingwith the evacuation and retarding desiccation thereof.

39 indicates a pedal piece. This pedalpiece is connected with the arms33 on the seat 3 by the rods 40, and it is designed as a convenientmeans for opening the commode when medicated paper or other disinfectantis to be placed therein.

Then desirable, it is obvious that a disinfectant or a disinfectantcommingled with sand or dry earth may be used in lieu of sand or dryearth in my improved commode.

Then desirable, the shutters 25 may be so connected with the uprights 28that when considered unnecessary, as in publie commodes, they may bereadily removed and dispensed with. I generally prefer, however, toemploy the said shutters for the purpose before stated.
